The large earthquake rattled residents in the southwest of the Andean nation, but there were no reports of deaths or major damage, authorities said.

"The USGS has received lots of reports that the quake was felt, but no reports of damage or injuries," USGS geophysicist Paul Caruso told NBC News.

The quake was centered 28 miles (45 km) south of Popayan, Colombia, close to the Ecuador border, with a depth of about 103 miles, Colombian officials said.

Its preliminary magnitude of 7.4 was later updated to 7.2, and then 7.1.

"So far there are no reports that there has been damage to any part of the country, only reports that it was felt," Jaime Raigosa, coordinator of the National Seismological Network, said. "Fortunately, the quake was deep."

The quake struck at 11:31 a.m. local time. It was centered at a depth of about 103 miles, Colombian officials said.

The quake was felt in neighboring Ecuador but authorities reported no damage there.
